func MergeVersioningData(a *persistencespb.VersioningData, b *persistencespb.VersioningData) *persistencespb.VersioningData

MergeVersioningData merges two VersioningData structs. If a build ID appears in both data structures, the merged structure will include that latest status and timestamp. If a build ID appears in different sets in the different structures, those sets will be merged. The merged data's per set default and global default will be set according to the latest timestamps in the sources. if (a) is nil, (b) is returned as is, otherwise, if (b) is nil (a) is returned as is.

func UpdateVersionSets added in v1.21.0 

func UpdateVersionSets(clock *hlc.Clock, data *persistencespb.VersioningData, req *workflowservice.UpdateWorkerBuildIdCompatibilityRequest, maxSets, maxBuildIds int) (*persistencespb.VersioningData, error)

UpdateVersionSets updates version sets given existing versioning data and an update request. The request is expected to have already been validated.

See the API docs for more detail. In short, the versioning data representation consists of a sequence of sequences of compatible versions. Like so: 

                     *
┬─1.0───2.0─┬─3.0───4.0
│           ├─3.1
│           └─3.2
├─1.1
├─1.2
└─1.3

In the above example, 4.0 is the current default version and no other versions are compatible with it. The previous compatible set is the 3.x set, with 3.2 being the current default for that set, and so on. The * represents the current default set pointer, which can be shifted around by the user.

A request may:

  1. Add a new version possibly as the new overall default version, creating a new set.
  2. Add a new version, compatible with some existing version, adding it to that existing set and making it the new default for that set.
  3. Target some existing version, marking it (and thus its set) as the default set.

Deletions are performed by a background process which verifies build IDs are no longer in use and safe to delete (not yet implemented).

Update may fail with FailedPrecondition if it would cause exceeding the supplied limits.

func VisibilityManagerProvider added in v1.21.0 

func VisibilityManagerProvider(
	logger log.Logger,
	persistenceConfig *config.Persistence,
	customVisibilityStoreFactory visibility.VisibilityStoreFactory,
	metricsHandler metrics.Handler,

	esClient esclient.Client,

	saProvider searchattribute.Provider,
) (manager.VisibilityManager, error)

type PhysicalTaskQueueKey added in v1.24.0 

type PhysicalTaskQueueKey struct {

PhysicalTaskQueueKey Each task queue partition corresponds to one or more "physical" (aka DB-level) task queues, each of which has a distinct physicalTaskQueueManager in memory in matching service, as well as a distinct identity in persistence.

Physical task queues with a version set or build ID are called "versioned". The ones without a version set or build ID are called "unversioned". A physical queue cannot have both version set and build ID.

unversioned: 			/_sys/<base name>/<partition id>

All versioned DB queues use mangled names, using the following format: 

with build ID: 		/_sys/<base name>/<build ID base64 URL encoded>#<partition id>
with version set: 		/_sys/<base name>/<version set id>:<partition id>

type TaskMatcher added in v0.6.0 

type TaskMatcher struct {
	// contains filtered or unexported fields
}

TaskMatcher matches a task producer with a task consumer Producers are usually rpc calls from history or taskReader that drains backlog from db. Consumers are the task queue pollers

func (*TaskMatcher) MustOffer added in v0.6.0 

func (tm *TaskMatcher) MustOffer(ctx context.Context, task *internalTask, interruptCh <-chan struct{}) error

MustOffer blocks until a consumer is found to handle this task Returns error only when context is canceled or the ratelimit is set to zero (allow nothing) The passed in context MUST NOT have a deadline associated with it Note that calling MustOffer is the only way that matcher knows there are spooled tasks in the backlog, in absence of a pending MustOffer call, the forwarding logic assumes that backlog is empty.

func (*TaskMatcher) Offer added in v0.6.0 

func (tm *TaskMatcher) Offer(ctx context.Context, task *internalTask) (bool, error)

Offer offers a task to a potential consumer (poller) If the task is successfully matched with a consumer, this method will return true and no error. If the task is matched but consumer returned error, then this method will return true and error message. This method should not be used for query task. This method should ONLY be used for sync match.

When a local poller is not available and forwarding to a parent task queue partition is possible, this method will attempt forwarding to the parent partition.

Cases when this method will block:

Ratelimit: When a ratelimit token is not available, this method might block waiting for a token until the provided context timeout. Rate limits are not enforced for forwarded tasks from child partition.

Forwarded tasks that originated from db backlog: When this method is called with a task that is forwarded from a remote partition and if (1) this task queue is root (2) task was from db backlog - this method will block until context timeout trying to match with a poller. The caller is expected to set the correct context timeout.

returns error when:

  • ratelimit is exceeded (does not apply to query task)
  • context deadline is exceeded
  • task is matched and consumer returns error in response channel

func (*TaskMatcher) OfferNexusTask added in v1.24.0 

func (tm *TaskMatcher) OfferNexusTask(ctx context.Context, task *internalTask) (*matchingservice.DispatchNexusTaskResponse, error)

OfferNexusTask either matchs a task to a local poller or forwards it if no local pollers available. Local match is always attempted before forwarding. If local match occurs response and error are both nil, if forwarding occurs then response or error is returned.

func (*TaskMatcher) OfferQuery added in v0.7.0 

func (tm *TaskMatcher) OfferQuery(ctx context.Context, task *internalTask) (*matchingservice.QueryWorkflowResponse, error)

OfferQuery will either match task to local poller or will forward query task. Local match is always attempted before forwarding is attempted. If local match occurs response and error are both nil, if forwarding occurs then response or error is returned.

func (*TaskMatcher) Poll added in v0.6.0 

func (tm *TaskMatcher) Poll(ctx context.Context, pollMetadata *pollMetadata) (*internalTask, error)

func (*TaskMatcher) PollForQuery added in v0.6.0 

func (tm *TaskMatcher) PollForQuery(ctx context.Context, pollMetadata *pollMetadata) (*internalTask, error)

type UserDataUpdateOptions added in v1.21.0 

type UserDataUpdateOptions struct {
	TaskQueueLimitPerBuildId int
	// Only perform the update if current version equals to supplied version.
	// 0 is unset.
